UIS Objective Lens

After the Second World War, Olympus developed various objective lens series, including the Plan series, Mplan series, and the LB series of long barrel objective lenses. The company also launched infinity corrected (IC) long barrel objective lenses for industrial applications, further expanding its line-up.
In 1988, Olympus took the momentous decision to switch all its microscope models to a new universal infinity system (UIS) optics.
The new UIS optical system was based on the concept of an ideal microscope to meet all needs and incorporated the following features:

• Provides world-class resolution and contrast for all observation methods.
• Uses infinity optics to unify the design concepts for biological and industrial systems. Ensures excellent scalability of modular components.
• Creates a universal objective lens line-up, as this single objective lens series can be used for all types of observation methods.
• Field of view for standard observations expanded to 22 (the field of view is a unit expressing the breadth of view). Improves operability by expanding the range across which the objective lens can move.

The development and manufacturing teams at Olympus had given their all on this product. When they finally completed their work, they had achieved a novel design, developed more appropriate glass materials, developed thin-film coatings (multiple coats), achieved reliable product quality, and developed automated lens processing methods to lower costs.
The UIS objective lens series was launched in 1993. The UIS objective lenses contributed to greater product appeal in the AX, BX, and CX series, as well as the IX series of microscopes.
